Uncaught [TypeError: Cannot read property 'Product2' of undefined] in lightning design system

Helper
  
setBillingCatCalc : function(cmp, oli) {
        $A.log('running Abstract helper');
        $A.log('billcatcalcs: '+cmp.get("v.billingCatCalcs"));
        $A.log('oli: '+cmp.get("v.oli"));
        
        if (oli.PricebookEntry.Product2  !== undefined && oli.PricebookEntry.Product2.Billing_Category__c !== undefined) {
            cmp.set("v.billingCatCalcs",oli.PricebookEntry.Product2.Billing_Category__c.split(";"));
        }
        var calcBCC = oli.Billing_Category__c+'_'+oli.BillingCalc__c;
        cmp.find("selBCC").set("v.value",calcBCC);
        cmp.set("v.oli",oli);
    }

Product2 is not the problem. Your oli list does not have PricebookEntry record that is why it is undefined and the error says there is no product2 for undefined. Change the if condition to check wheather PricebookEntry record is coming or not 
if(oli.PricebookEntry !== undefined)
